Codeigniter中电话号码的正则表达式

Question

I am using codeigniter and I want to check user input with regular expression for phone number. My pattern is [+]zero or one and [0-9] number.
Following format,
+959250142935
09250142935
This is my pattern - /\\+?[0-9]$/
This does not work as I expected.

Answer 1

You can use the following pattern to check for valid phone number. There is a additional {5,} to set a minimum length of the phone number (in this case 5), so the phone number can't be a single number:

^[\\+]{0,1}[0-9]{5,}$ or ^[\\+]{0,1}\\d{5,}$

You can use this pattern directly on the <input> :

<input pattern="^[\+]{0,1}[0-9]{5,}$" type="text"/>
<input pattern="^[\+]{0,1}\d{5,}$" type="text"/>

Answer 2

Try with this regex

/^(\\+|0|1)\\d+$/

If the number must be certaing length

/^(\\+|0|1)\\d{10}$/
